¿Qué es un QUARK?

The video tutorial explores the discovery of the neutron in 1932 and the subsequent belief that no more particles existed. However, in the 1950s, new particles with properties similar to protons and neutrons were discovered, leading to the development of the quark model. This model proposed that protons, neutrons, and other particles were composed of quarks, which are elementary particles. The video explains the types of quarks, their properties, and the extensions of the quark model, including the discovery of charm, bottom, and top quarks. It also discusses quark interactions, such as the strong interaction, and their significance in quantum dynamics and the standard model of particle physics.

What was the initial belief about particles after the discovery of the neutron in 1932?

• That particles could be divided into simpler components.

• That there were many more particles to be discovered.

• That no more particles existed beyond protons, neutrons, and electrons.

• That particles were not fundamental.
